Instead of creating XML UI description language similar to KML, I chose .INI files for ease of use by designers/users.
Ditched Nano-X for a significantly lighter custom image handler.
Allows fully custom graphics, command lines, submenu definitions.
Has fake "fip" and "khwl" drivers, using SDL to emulate the relevant hardware (keys, OSD) on a PC.
Ported to use the MG-35 osdtest/khwl/fip hardware. Fortunately, this was easy.
New menu INI file image loader uses image cache for smaller memory footprint.
Reads all .ini files from /etc/menu.d, starting with main.ini.

Usage

INI files

The menu interface is defined by a group of INI files located under /etc/menu.d. The format of these INI files is as follows:

[sectname]       -- Some arbitrary section name.  Purely descriptive.
mode=<MODE>      -- Composite or Flat mode
composite: Use the standard menu item{hi,lo,off} background
with image{hi,lo,off} composited on top
flat     : Just use the image{hi,lo,off} image.
menu=<MENU>      -- Containing menu name
main     : top level menu
anything else is the name of a submenu
order=<N>        -- What item # in the given menu
imagehi=<PNG>    -- Selected menu item image (active menu)
imagelo=<PNG>    -- Selected menu item image (inactive menu)
imageoff=<PNG>   -- Unselected menu item image
cmd=<CMD>        -- Command line to execute the item
submenu=<MENU>   -- Submenu to display upon selection

A special file, main.ini, contains the main menu definition:

[Main]
header=<IMG>        -- Main menu header
imagehi=<IMG>       -- Selected button background (active menu)
imagelo=<IMG>       -- Selected button background (inactive menu)
imageoff=<IMG>      -- Unselected button background
submenu=main        -- Defines the main menu
